Umthengi waseSri Lanka: I-8T/ngosuku, ikesi yeprojekthi yokucoca i-sodium silicate enobushushu obuphezulu

I. Imvelaphi yeProjekthi: Iimfuno eziphambili zokuhluza i-sodium silicate enobushushu obuphezulu

I-sodium silicate sisixhobo esibalulekileyo sekhemikhali esingasetyenziswanga esisetyenziswa kakhulu kumashishini afana neesepha, ulwakhiwo, kunye neempahla zelaphu. Umthengi kule ntsebenziswano lishishini leekhemikhali elaziwayo eSri Lanka, elibandakanyeka kakhulu kwimveliso kunye nokuthengiswa kweemveliso zochungechunge lwe-sodium silicate. Ngokwanda kwemfuno yemarike, izixhobo zokucoca zokuqala zomthengi azikwazanga ukuhlangabezana neemfuno zemveliso, zijongene nemingeni emininzi yobugcisa.

Imfuno ephambili yomthengi icacile: ukufezekisa ukuhluzwa okuzinzileyo kweetoni ezi-8 ze-sodium silicate ngosuku, kunye nobushushu bokuhluzwa obuhlala bukwi-80℃. I-sodium silicate ineempawu ze-viscosity ephezulu kunye ne-crystallization elula kumaqondo obushushu aphezulu, kwaye i-slurry yokuqala inezingcola ze-silicate ezinganyibilikiyo ezifana ne-iron, i-aluminium, i-calcium, kunye ne-magnesium. Ukuba ukuchaneka kokuhluzwa akwanelanga, kuya kuchaphazela kakhulu ubunyulu bemveliso, ngaloo ndlela kuchaphazele ukusetyenziswa kwabathengi abasezantsi. Kwangaxeshanye, umthengi ufuna ukuba inkqubo yokuhluza isebenze ngokufanelekileyo nangokuzinzileyo, inokunciphisa iindleko zokugcinwa ngesandla, kwaye ihambelana nemigangatho yokhuseleko lokusingqongileyo kunye nemveliso yendawo.

II. Isisombululo:Inkqubo yokucoca uxinzelelo eyenziwe ngokwezifiso + inkqubo yokucoca ipompo yesikrufu

Ukuphendula kwiimfuno zomthengi zokucoca izinto ezishushu kakhulu nezinobukrakra, kunye neempawu zezinto zesodium silicate, senze isisombululo sokucoca esidibeneyo esine-pressure filter esebenzayo njengesiseko kunye ne-screw pump ezinikeleyo njengesongezelelo. Ukususela ekukhetheni izixhobo, ukuphucula inkqubo ukuya ekudityanisweni kwenkqubo, siqinisekisa ngokupheleleyo isiphumo sokucoca kunye nokusebenza kakuhle kwemveliso.

1. Ukukhetha izixhobo eziphambili: Isihluzi soxinzelelo esifanelekileyo kwiimeko zobushushu obuphezulu

Xa sijonga imeko yobushushu obuphezulu obungama-80℃, iipleyiti zesihluzo se-polypropylene eziqhelekileyo zinokuguquguquka. Sikhethe isihluzo soxinzelelo lwezinto zentsimbi engagqwaliyo ezingama-316L. Esi sixhobo sinokumelana nokugqwala okunamandla kunye nokusebenza kakuhle kobushushu obuphezulu, okunokuthintela ngempumelelo ukuguquguquka kwepleyiti yesihluzo kunye neengxaki zokuvuza phantsi kweemeko zobushushu obuphezulu. Kwangaxeshanye, ngokusekelwe kumthamo wokucubungula wemihla ngemihla weetoni ezi-8, indawo yokucoca ibalwe ngokuchanekileyo, kwaye ubungakanani begumbi lesihluzo kunye neenkcukacha zelaphu lesihluzo ezihambelanayo zacwangciswa - ilaphu lesihluzo lisebenzisa izinto ze-polypropylene ezimelana nobushushu obuphezulu, ezinobukhulu be-pore obuncinci kancinci kunexabiso le-D90 lokungcola okujoliswe kuko, ezinokubamba ngokufanelekileyo ukungcola ngelixa ziqinisekisa izinga lokuhamba kokucoca kwaye ziphephe into "ebalekayo".

Ukuphucula ngakumbi ukusebenza kakuhle kokuhluza, inkqubo yesihluzi soxinzelelo ibandakanya itekhnoloji yokulawula umahluko woxinzelelo. Xa umahluko woxinzelelo lwangaphakathi nolwangaphandle lwesixhobo sokuhluza ungaphezulu kwe-0.2MPa, inkqubo ilungisa ngokuzenzekelayo uxinzelelo kwindawo yokukhupha ulwelo lwesihluzi ukuze kugcinwe umahluko woxinzelelo ngaphakathi koluhlu olukhuselekileyo, yandisa ngempumelelo umjikelo wokuhluza kwaye yonyusa umthamo kunye nesantya sokuhluza. Ukongeza, izixhobo zixhotyiswe ngenkqubo yolawulo oluzenzekelayo, olunokufezekisa ukucinezelwa ngokuzenzekelayo, ukukhupha, kunye nokunciphisa kakhulu amandla okusebenza ngesandla.

2. Ukuhambelana kwenkqubo yokuhambisa: Impompo yesikrufu ezinikeleyo iqinisekisa ukondla okuzinzileyo

I-sodium silicate slurry ine-viscosity ephezulu kwaye iqulethe ukungcola okuqinileyo. Iipompo zokuhambisa eziqhelekileyo zinokuthintela ukuvaleka nokuguguleka. Sinike umthengi ipompo yesikrufu engagugiyo, enokuhamba okuzinzileyo kunye nokuphefumla okuncinci koxinzelelo, kwaye inokuhlangabezana neemfuno zokuhambisa zezinto ezinobungqindilili obuphezulu kunye neziqulathe amasuntswana. Isantya sokujikeleza sepompo yesikrufu sinokulungiswa ngokuguqulwa rhoqo ukuze kuhambelane ngokuchanekileyo nesantya sokondla sefiltha yoxinzelelo, kuthintelwe ukuvaleka kweplate yesihluzo ngenxa yesantya sokondla esigqithisileyo okanye kuchaphazele ukusebenza kakuhle kwemveliso ngenxa yesantya sokondla esinganelanga. Kwangaxeshanye, umzimba wepompo kunye nombhobho wokuhambisa zixhotyiswe ngee-ceramic liners ezingagugiyo ukuphucula ukumelana nokuguguleka kunye nokwandisa ubomi benkonzo yesixhobo.
